Nimbus has a branch
- Eitan Seri-Levi
Lighthouse has one. Interops with lodestar and teku
- Barnabas
oh nice
- Barnabas
we should only need couple more ELs then
- Guru
Reacted to "Nimbus has a branch" with 👍
- Nico Flaig
we should test slashing validators before the fork this time to properly test 8045
- Barnabas

For EL devs, `glamsterdam-devnet@v6.0.0` released on Friday: https://github.com/ethereum/execution-specs/releases/tag/tests-glamsterdam-devnet%40v6.0.0 There's another release expected tomorrow with additional coverage for 8037/8038!
- Barnabas
I think we would have a good solid chance to have devnet 7 to be our final devnet btw
- Toni Wahrstätter
imo, the strongest argument is that it keeps on-chain proofs against the beacon root stable. The fact that it allows us avoiding bumping some constants (e.g. 8192 deposits) is a less strong argument.
- Toni Wahrstätter
how long will including this EIP delay things for those clients that don't have it yet?
- Dustin
Toni: I agree actually, that the stability is the stonger point longer-term
- Justin Traglia
Reacted to "imo, the strongest a..." with 👍
- Barnabas
we should have a final scope before we doing edge case testing
- Barnabas
otherwise the edge case testing is redundant
- Nico Flaig
will there be a public temporary testnet like we had with mekong for electra?
- Bharath
Replying to "we should have a fin..." We should definitely do builder-api testing at least in devnet-7
- Justin Florentine (Besu)
Reacted to "will there be a publ..." with ➕
- Bharath
I understand that clients would have been more focused on EIP-8282 for devnet-6 but I think scoping builder-api for devnet-7 would be reasonable IMO
- Barnabas
I’d prefer to have some vibe check on today’s call.
